以污水处理为中心的循环经济体系构建研究

Study on the Construction of Circular Economy Centered by Sewage Treatment

以循环经济为理论基础,以造纸业作为实现人工湿地芦苇纤维素资源化的生产系统,构建了以污水处理为中心的循环经济体系。研究结果表明,芦苇人工湿地对农业退水、生活污水、剩余污泥具有较为显著的净化功效。基于试验结果,分析了所构建的循环经济体系在芦苇人工湿地取得显著净化效果条件下的技术、经济、环境可行性。

Based on the theory of circular economy, and reutilization of Phragmites australis cellulose planted in constructed wetland to paper industry, the mode of circular economy centered by sewage treatment was constructed. The results of trial indicated that the efficacies of constructed wetland planted with Phragmites australis in treatment of agriculture waste water, domestic sewage and excess sludge were higher. According to the results of trial, the feasibility of technology, economy and environment of this circular economy were investigated under Lhe condition that the treatment efficacies of constructed wetland planted with Phragmites australis were higher.
